          +-----------+-----------+
          |    [ Control Node ]   |
          |                       |

          +-----------------------+
[1] Install Nova services.
root@dlp ~(keystone)#
apt-get -y install nova-api nova-placement-api nova-conductor nova-consoleauth nova-scheduler nova-novncproxy python-novaclient
[2] Configure Nova.
root@dlp ~(keystone)#
mv /etc/nova/nova.conf /etc/nova/nova.conf.org

root@dlp ~(keystone)#
vi /etc/nova/nova.conf
# create new

[DEFAULT]
# define own IP
my_ip = 10.0.0.30
state_path = /var/lib/nova
enabled_apis = osapi_compute,metadata
log_dir = /var/log/nova
# RabbitMQ connection info
transport_url = rabbit://openstack:password@10.0.0.30

[api]
auth_strategy = keystone

# Glance connection info
[glance]
api_servers = http://10.0.0.30:9292

[oslo_concurrency]
lock_path = $state_path/tmp

# MariaDB connection info
[api_database]
connection = mysql+pymysql://nova:password@10.0.0.30/nova_api

[database]
connection = mysql+pymysql://nova:password@10.0.0.30/nova

# Keystone auth info
[keystone_authtoken]
www_authenticate_uri = http://10.0.0.30:5000
auth_url = http://10.0.0.30:5000
memcached_servers = 10.0.0.30:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = servicepassword

[placement]
auth_url = http://10.0.0.30:5000
os_region_name = RegionOne
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = placement
password = servicepassword

[placement_database]
connection = mysql+pymysql://nova:password@10.0.0.30/nova_placement

[wsgi]
api_paste_config = /etc/nova/api-paste.ini
root@dlp ~(keystone)#
chmod 640 /etc/nova/nova.conf

root@dlp ~(keystone)#
chgrp nova /etc/nova/nova.conf

[3] Add Data into Database and start Nova services.
It doesn't need to care the messages "deprecated ***" when sync DB.
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage api_db sync"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage cell_v2 map_cell0"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage db sync"
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage cell_v2 create_cell --name cell1"
root@dlp ~(keystone)#
systemctl restart apache2

root@dlp ~(keystone)#
for service in api conductor scheduler consoleauth novncproxy; do
systemctl restart nova-$service
done
# show status

root@dlp ~(keystone)#
